In CentOS 5, I directly edit iptables file.
I'm using the following DNS rules for iptables (as suggested by
RH/CentOS), and I have no problems with DNS servers:
-A RH-Firewall-1-INPUT -m state --state NEW -p udp --dport 53 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -p tcp --dport 53

Personally I wouldn't put a DNS server behind any stateful firewall at
